As the game‘s name implies, players will be tasked with fighting off an invasion of Tyranids, a race of insect-like creatures. To do so, you’ll control a team of the franchise’s iconic space marines as you battle through 40 missions at the edge of Imperial space.

As you fight your way through the game, you’ll gain experience points that can be used to level up your space marines and unlock new skills. And the game has plenty to offers collectors as well, with 38 different Deathwatch Space Marines and over 150 weapons and wargear items to collect.

Warhammer 40,000: Deathwatch — Tyranid Invasion will be free through February 25, so hit up the app Store link below to start your campaign as a space marine.
